An Average Wavelength Parameter for Surface Metrology

open access: yesMeasurement + Control, 1972
The new International Standard for the assessment of surface texture is based on the Arithmetic Average Height Index R a . This parameter, although extremely valuable for quality control in manufacture, takes little or no account of the openness or ...

Using benzene carboxylic acids to prepare zirconium-based catalysts for the conversion of biomass-derived furfural

open access: yesInternational Journal of Coal Science & Technology, 2017
Benzene carboxylic acid (BCAs) are common and useful chemical blocks, which can be derived from the abundant low rank coals (LRCs) via oxidative degradation. In this work, we proposed a novel strategy to utilize BCAs as raw materials to prepare catalysts

Proportional Rankings [PDF]

open access: yesProceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence, 2017
We extend the principle of proportional representation to rankings: given approval preferences, we aim to generate aggregate rankings so that cohesive groups of voters are represented proportionally in each initial segment of the ranking. Such rankings are desirable in situations where initial segments of different lengths may be relevant, e.g., in ...

A note on the gap between rank and border rank [PDF]

open access: yes, 2017
We study the tensor rank of the tensor corresponding to the algebra of n-variate complex polynomials modulo the dth power of each variable. As a result we find a sequence of tensors with a large gap between rank and border rank, and thus a counterexample

Evaluation and selection of CORDEX-SA datasets and bias correction methods for a hydrological impact study in a humid tropical river basin, Kerala

open access: yesJournal of Water and Climate Change, 2021
It is well recognised that the performance of climate model simulations and bias correction methods is region specific, and, therefore, careful validation should always be performed.
